4.4. Setting CANbus rate
The iPOS4808 drives accept the following CAN rates: 125Kbps, 250 Kbps, 500kbps and 1Mbps.
Using the Drive Setup dialogue you can choose the initial CAN rate after power on. This
information is stored in the setup table The CAN rate is initialized using the following algorithm:
a) If a valid setup table exists, and this setup table was created with the Set baud rate
checkbox checked in the Drive Setup dialogue (see above) – with the value read from the
setup table. This value can be one of the above 4 values or the firmware default (F/W
default) which is 500kbs
b) If a valid setup table exists, and this setup table was created with the Set baud rate
checkbox unchecked in the Drive Setup dialogue (see above) – with the last value set
either from a valid setup table or by a CANopen master via CiA-305 protocol
c) If the setup table is invalid, with the last value set either from a valid setup table or by a
CANopen master via CiA-305 protocol.
d) If the setup table is invalid, there is no previous CAN rate set from a valid setup table or by
a CANopen master, with f/w default value which is 500kbs
